What
kind of statement is that supposed to be? The President claims there
was no species yet which has been able to prevent its extinction. That
statement is clearly wrong, because every species existing on Earth
prevented its own extinction yesterday. How can you know when
"extinction" is to take place? If I take a deep breath, because I need
Oxygen for living, I was in possession of the knowledge to prevent my
own extinction. You can only know about a certain moment when a species
failed to prevent its extinction, but every second a species is not being wiped out, it is successfully doing so.
